Cities in Polk County ADU Rules (2026)

Incorporated cities may have rules that differ from the county. Click a linked city for its specific ordinance.

  • Lakeland
  • Winter Haven
  • Haines City
  • Auburndale
  • Bartow
  • Davenport
  • Lake Wales

Eight to fourteen weeks and $1,500 to $2,800. That is what Polk County’s Planning & Development office in Bartow typically takes, and charges, to get a 600 sq ft ADU from a complete application to a permit, impact fees included, and both figures are the lowest in the nine counties this site covers. They sit on top of a Land Development Code that already permits “accessory living quarters” in most residential zones, allows detached and attached configurations alike, and does not prohibit an independent kitchen. The cap is 1,000 sq ft of heated floor space, with a 25 ft height limit and one additional parking space. Under current code, Polk is the most forgiving county in the region for an ADU project.

With SB 48 dead for 2026, any further loosening (removing owner-occupancy on larger parcels is the one people ask about) would have to come through Polk’s own ordinance process. If you want the statewide background, it is on the Florida ADU law page.

Polk is the fastest-growing county in our coverage area by percentage, with the Lakeland–Haines City–Davenport corridor absorbing significant population from both Orlando and Tampa commuters. ADUs here are a practical middle-housing response and are supported by county leadership in public comments.

Incorporated cities in Polk County with their own ADU rules:

  • Lakeland ADU Rules (2026): Polk County’s largest city; Urban area geographic gate applies; transportation impact fees exempt (~$754 total); kitchens and owner-occupancy require direct confirmation with Planning
Lakeland is not an administrative permit Unlike the unincorporated county, Lakeland requires compatibility review by the Planning and Zoning Board for an ADU — not a straightforward over-the-counter permit. Budget for a hearing timeline, not just a plan-review timeline, if your parcel is inside city limits.

Permit throughput

Polk’s Planning & Development office processes ADU applications in 8–14 weeks on average, which is the fastest in our coverage area. Fees are also among the lowest, at $1,500–$2,800 total for a 600 sq ft ADU including impact fees. Combined with the relatively low land and construction costs in Polk compared to Orange or Seminole, this makes Polk one of the better-penciling counties for ADU projects intended as long-term rental income.
